Super-high-rise building rainwater micro power generation system

Abstract

The invention discloses a super-high-rise building rainwater micro power generation system. The system aims at achieving high-efficiency power generation of high-potential energy rainwater through low-cost equipment. The system comprises a rainwater collecting tank, a rainwater circulating pipeline and a power generation device which communicate with one another in sequence, wherein the rainwatercollecting tank is fixed at the top of a building, the rainwater circulating pipeline is vertically arranged on the side wall of a building body, and extends to the bottom of the building, and a wateroutlet of the rainwater circulating pipeline is provided with a nozzle used for controlling the water flow speed; the power generation device comprises a power generator and a micro-turbine which arearranged in a coupling mode, a volute chamber of the micro-turbine is spiral, and the micro-turbine is provided with a water inlet pipe and a water outlet pipe in the vertical direction, wherein thewater inlet pipe is arranged in the direction far away from the central axis of the micro-turbine, and the water outlet pipe is arranged in the direction of the central axis of the micro-turbine; andthe water inlet pipe communicates with the nozzle, and the water outlet pipe communicates with a water outlet guide pipe. According to the super-high-rise building rainwater micro power generation system, resistance of the turbine to water flow can be obviously reduced, the operation effect and the generating capacity of a water turbine are improved, and remarkable economic and social benefits areachieved.

Description

technical field [0001] The invention relates to the technical field of clean energy utilization, in particular to a rainwater miniature power generation system for super high-rise buildings, which can significantly reduce energy loss in the rainwater power generation process and obtain greater power generation. Background technique [0002] With the development of my country's economy and society and the construction of modern cities, the number of urban super high-rise buildings is increasing rapidly, not only extending to higher space, but also expanding in scale. In terms of regional distribution, the construction of super high-rise buildings has been shifting from economically developed coastal areas to inland cities, and from first-tier cities such as Beijing, Shanghai, and Guangzhou to second- and third-tier cities. According to incomplete statistics, my country currently has more than 1,100 super high-rise buildings that have been built, are under construction or are ...

Problems solved by technology

At the same time, as the floor height increases, the gravitational potential energy of the rainwater discharged from the sewer pipes also increases. Due to the lack of necessary energy-saving and environmental protection measures, the available gravitational potential energy disappears, and the available water resources Also wasted in vain

However, in the current existing technologies, the efficiency of rainwater power generation is low, the cost is high, and it is difficult to popularize
